Overrides javafx.scene.control.cell.TextFieldTableCell.cancelEdit.

Doc from javafx.scene.control.cell.TextFieldTableCell.cancelEdit.

Cancels an edit to the value of the cell. Call this function to transition from an editing state into a non-editing state, without saving any user input.

Overrides javafx.scene.control.TableCell.commitEdit.

Doc from javafx.scene.control.TableCell.commitEdit.

Commits an edit to the value of the cell. Call this function when appropriate (based on the user interaction requirements of your cell editing user interface) to do two things:

1. Fire the appropriate events back to the backing UI control (e.g., ListView). This will begin the process of pushing this edit back to the relevant data source / property (although it does not guarantee that this will be successful - that is dependent upon the specific edit commit handler being used). Refer to the UI control class javadoc for more detail.
2. Begin the transition from an editing state into a non-editing state.

In general there is no need to override this method in custom cell implementations - it should be sufficient to simply call this method when appropriate (e.g., when the user pressed the Enter key, you may do something like cell.commitEdit(converter.fromString(textField.getText()));

@Override

Overrides javafx.scene.control.cell.TextFieldTableCell.startEdit.

Doc from javafx.scene.control.cell.TextFieldTableCell.startEdit.

Starts an edit to the value of the cell. Call this function to transition from a non-editing state into an editing state, if the cell is editable. If this cell is already in an editing state, it will stay in it.

Overrides javafx.scene.control.cell.TextFieldTableCell.updateItem.

Doc from javafx.scene.control.cell.TextFieldTableCell.updateItem.

The updateItem method should not be called by developers, but it is the best method for developers to override to allow for them to customise the visuals of the cell. To clarify, developers should never call this method in their code (they should leave it up to the UI control, such as the javafx.scene.control.ListView control) to call this method. However, the purpose of having the updateItem method is so that developers, when specifying custom cell factories (again, like the ListView cell factory), the updateItem method can be overridden to allow for complete customisation of the cell.

It is very important that subclasses of Cell override the updateItem method properly, as failure to do so will lead to issues such as blank cells or cells with unexpected content appearing within them. Here is an example of how to properly override the updateItem method:

protected void updateItem(T item, boolean empty) {
    super.updateItem(item, empty);

    if (empty || item == null) {
        setText(null);
        setGraphic(null);
    } else {
        setText(item.toString());
    }
}

Note in this code sample two important points:

1. We call the super.updateItem(T, boolean) method. If this is not done, the item and empty properties are not correctly set, and you are likely to end up with graphical issues.
2. We test for the empty condition, and if true, we set the text and graphic properties to null. If we do not do this, it is almost guaranteed that end users will see graphical artifacts in cells unexpectedly.
